Melatonin was most frequently prescribed in children for a longer duration than other hypnotics, while MRAs were prescribed across all age groups and DORAs mainly to adolescents. These age-specific patterns suggest that the drug selection was conducted according to patient's age, since pediatric insomnia might be correlated with psychiatric disorders related to developmental stage. Future research should investigate the long-term effects of hypnotic prescriptions with consideration of comorbid conditions.
